钢筋砼迭合构件正常使用极限状态的计算

Calcutation of Serviceability Limite for Reinforced Concrete Composite Members

本文根据钢筋砼迭合式受弯构件的截面应力重分布,提出迭合构件在标准荷载下的纵筋应力σ_8、最大裂缝宽度 W_(max)及短期刚度 B_(82)的计算方法。

Based on the redistribution of section stresses in reinforced concrete composite members,this paper puts forward the calculating method of reinforcement stress σ_、maximum crack width W_(max)and short —time stiffness B_(2)for the members in standard load
